12V car battery and charging-system tester

The battery is being charged and discharged continuously during the course of using. Its capacity reduced can cause the failure of starting the automobile engine. Thus it is very important to judge the battery's capacity,but it not easy voltage meter to measure the battery's voltage. So it is a better method to use battery tester to measure the capacity of the battery
Battery tester combines measuring instrument and load together, meanwhile a correspond colorful dial with scale is attached It enables the measuring and judgement of the battery to be more precise and reliable in the condition of simulating the battery's working.It can measure the voltage while the battery is being charged.
The charging system can be tested by its voltage through this tester, just analysed by colored dial plate! And the tester can test the auto-motor elementary.
